Background: Vaccination has saved millions of lives through the protection of individuals and populations from communicable diseases. Vaccine hesitancy, defined as the delay in acceptance or refusal of vaccines despite the availability of vaccination services, has become a growing global concern. The objective of this study was to investigate parents'/caregivers' hesitancy toward childhood vaccination and its predictors in Albania., Study Design: A cross-sectional survey was conducted., Methods: The data comes from a survey conducted on a sample of parents/caregivers (89.6% mothers) of children aged 6 months to 8 years at health care vaccination centers in seven Albanian cities from December 2020 to February 2021. Parents/caregivers (one per child) were interviewed by trained healthcare staff using a standardized questionnaire on six main content domains, including immunization behavior, beliefs about vaccine safety and efficacy, attitudes about vaccines, vaccination confidence, estimation of vaccine delay, and the intention to immunize children against SARS-CoV-2, and a self-reported hesitancy. The Albanian Ministry of Health approved the questionnaire, after it was translated, validated and adapted to the local setting. Statistical analyses included independent sample t-tests (p<0.05) and a logistic regression (OR; 95% C.I.)., Results: A total of 475 parents/caregivers of children aged from 6 months to 8 years, attending childhood vaccination in public health services, were interviewed. To the question "how hesitant you are about childhood vaccination", a high number of parents/caregivers (46%) responded that they do not feel hesitant at all, and 32% were not hesitant, a small number of parents/caregivers said they are very hesitant (5%) or somewhat hesitant (12%). A binary logistic model was fitted to the data to test the hypothesis regarding the relationship between parental vaccine hesitancy and possible predictors. A lower parental attitude toward childhood vaccines (OR = 3.7; 95% C.I. 1.102-12.421), a health center with a high vaccine delay (OR = 2.878; C.I. 95% 1.735-4.773), and low confidence in health staff information (OR = 2.042; 95% C.I. 1.156-3.605) were all independent predictors of parental vaccine hesitancy. Regarding intention to vaccinate children against COVID-19, when available, nearly 75% of parents/caregivers showed hesitancy., Conclusions: Our results highlighted the role of positive parents'/caregivers' attitudes toward childhood vaccines followed by high staff confidence and good health center organization in order to deal with vaccine hesitancy, particularly for traditional and well-known childhood vaccines. Nevertheless, the hesitancy can be a critical barrier for childhood vaccination when we have to introduce a new vaccine, as is demonstrated in the recent vaccination campaign against the ongoing pandemic of SARS-CoV2.

Gastroenteritis is one of the most important diseases in developing country and viral infections are well documented. To understand better the epidemiological aspect of gastroenteritis in Albania and especially viral gastroenteritis, one-year study was carried out with the cooperation of physicians working in the Paediatric Hospital in University Hospital Center "Mother Thereza" in Tirana. Three hundred thirteen stool samples were collected from children with diarrhoea and a questionnaire was filled by the health personnel for each child. Analysis of the questionnaires revealed that overcrowding families and the limited availability of drinking water at home were risk factors for gastroenteritis. All the tests for enteroviruses were carried out using the molecular methods. One hundred and forty-seven out of three hundred thirteen stool samples showed a specific amplification band for one of the enteric viruses: astrovirus, adenovirus, rotavirus, and norovirus with an overall positive specimen rate of 46.9%. Rotavirus was the most frequent virus identified in 105 out of 147 samples (71.4%), astrovirus in 5 (3.4%), norovirus in 19 (12.9%), and enteric adenovirus in 18 (12.3%) samples. Double infection was present only in 14 samples (9.5%). The data suggest an evident circulation of viruses involved in gastroenteritis with a higher prevalence of rotavirus., ((c) Wiley-Liss, Inc.)

Albania is a Balkan country in South-Eastern Europe which, in recent years, has undergone complex demographic, political and economical changes. A notable drop in infant and maternal mortality rates and a significant rise in economic indicators have been observed in recent years. Despite this, over 15% of the population living in the northern and north-eastern areas of the country lives in extreme poverty conditions. In recent years various healthcare system reforms have been introduced, including the introduction of private healthcare and improvement of the main hospital infrastructures but not much has been done to increase the provision of essential healthcare services especially in rural and poor areas. Inequalities in health care are therefore widespread and these particularly affect children living in critical areas. In this paper we describe a paediatric healthcare intervention programme conducted in Albania from 2002 to 2004, aimed at improving the health and nutrition status of children and tackling healthcare system inequalities. The intervention consisted in offering free healthcare services and assistance, delivered through the Albanian healthcare system, to 5280 children. It also involved a health education programme for the mothers. The impact of the programme on the prevalence of infant malnutrition was evaluated by examining the medical records of 1745 infants followed for at least 6 months. Prevalence of malnutrition significantly decreased, from 13.4% to 4.2% during the study period. Mortality in children aged 0-5 years also showed a considerable drop. These results confirm that an efficient and sustainable model of paediatric healthcare assistance in Albania is possible.

Hepatitis A disease is endemic in Albania even though records from the Medical Authority show outbreaks involving only limited numbers of people. In the city of Lac, 200 people became ill following an outbreak of hepatitis A started on November 2002. The age distribution of the cases shows a peak in the age group 5-9 (43.5%) followed by the age group 10-14 (28%) and the age group 1-4 (18%). No cases were recorded in the age group 0-1. Drinking water and sewage samples were collected, using electropositive cartridges, during the outbreak. Rotavirus was identified by RT-PCR in two out of five drinking water samples; however, all the samples tested negative for HAV and astrovirus. Rotavirus was also identified in three out of five sewage samples from which four were HAV positive. HAV-RNA was identified in 28 (62.2%) out of 45 IgM anti-HAV positive sera collected during the outbreak. Genotype IA was expressed from all the amplified samples. Sequence analysis of the overlapping VP1-2A region shows 97-99% homology with three Italian strains IT-SCH-00, IT-ZAM-01, and IT-CAP-00 and one Spanish strain (Sa 30/06/95), whereas the phylogenetic tree built from the 168 bp sequence of the VP1-2A shows four clusters, one including 24 out of 28 RT-PCR positive sera. Considering the deduced amino acid sequence, only one substitution was identified and reported previously for genotype IB., (Copyright 2005 Wiley-Liss, Inc.)

Hepatitis A is a common disease in developing countries and Albania has a high prevalence of this disease associated to young age. In spite of the occurrence of a unique serotype there are different genotypes classified from I to VII. Genotype characterisation of HAV isolates circulating in Albania has been undertaken, as well as the study of the occurrence of antigenic variants in the proteins VP3 and VP1. To evaluate the genetic variability of the Albanian hepatitis A virus (HAV) isolates, samples were collected from 12 different cities, and the VP1/2A junction amplified and sequenced. These sequences were aligned and a phylogenetic analysis performed. Additionally, the amino half sequence of the protein VP3 and the complete sequence of the VP1 was determined. Anti-HAV IgM were present in 66.2% of all the sera. Fifty HAV isolates were amplified and the analysis revealed that all the isolates were sub-genotype IA with only limited mutations. When the deduced amino acid sequences were obtained, the alignment showed only two amino acids substitutions at positions 22 and 34 of the 2A protein. A higher genomic stability of the VP1/2A region, in contrast with what occurs in other parts of the world could be observed, indicating high endemicity of HAV in Albania. In addition, two potential antigenic variants were detected. The first at position 46 of VP3 in seven isolates and the second at position 23 of VP1 in six isolates., (Copyright 2004 Wiley-Liss, Inc.)

By the end of December 2000, the epidemiological system 'Alert' of the Public Health Institute in Tirane reported an outbreak of acute gastroenteritis. The outbreak involved children in Tirane and in the rural area. In total, 2722 children were seen in Tirane Hospital and 982 (56.4%) were treated for acute gastroenteritis. The age group with the highest morbidity was 0-5 years (89.7%), followed by the 6-9 (6.2%) and 10-15 years age groups (4.1%). The distribution of acute gastroenteritis cases, which occurred along the same water distribution system, suggests a waterborne origin. The nucleic acid amplification confirmed the co-circulation of different genotypes of rotavirus, mainly P[8]G9 and P[8]G3, responsible for the outbreak. Other enteric viruses such as astrovirus serotype 1, adenovirus and Norovirus, genogroups I and II were detected. Co-infections with different rotavirus genotypes and even with different enteric viruses were detected in several samples.

To develop a realistic model of the situation, a study was carried out in four different socioeconomic and hygienic areas of Tirane, namely in the modern and historical centre as well as in the intermediate and peripheral areas. In each area interviewers from the city's Public Health Directorate, contacted randomly, door-to-door, the residents, submitting a questionnaire and collecting water samples at the same time. Our data show relevant differences regarding distribution and quality of drinking water between the centre and peripheral areas. One third of water samples revealed the presence of microorganisms, whereas one fifth had no residual chlorine. Altogether more than 200,000 people in the peripheral areas of Tirane live under low level hygienic conditions. The recent outbreaks of cholera, poliomyelitis and the hyperendemic hepatitis A disease are the dramatic results of the low quality drinking water.

In order to assess child malnutrition, an anthropometric cross-sectional survey of children aged 0-36 months was conducted in selected rural, urban and mountainous areas of Northern Albania in May 1997. The results showed a high prevalence of low anthropometric indices in rural and mountainous areas with a trend of similar magnitude in northern rural areas. In Northern Albania child malnutrition is a public health priority. As the main risk factor for underweight we found a recent history of diarrhoea (OR = 2.45) together with female gender (OR = 2.28), rural (OR = 2.09) or mountain (OR = 1.61) residency. Absence of sanitation, marker of poor housing conditions, also showed a significant association (OR = 1.55) with underweight. Low birthweight (OR = 1.12) was confirmed as an important risk factor for underweight condition. In conclusion these findings underline the importance of support appropriate mother and child health and nutritional programmes in rural areas of Northern Albania.

Between April and December 1996, a serious outbreak of poliomyelitis occurred in Albania; almost 140 subjects were involved, and the episode presented an unusually high mortality rate (12%). During the outbreak, water samples from the Lana River in Tirana, Albania, and stool samples from two cases of paralytic poliomyelitis were collected and analyzed for the presence of polioviruses. Six polioviruses were isolated from the environmental and human samples, according to standard methods. All the samples were characterized by partial genomic sequencing of 330 bases across the 5' untranslated region (5'-UTR) (nucleotide positions 200 to 530) and of 300 bases across the VP1 region (nucleotide positions 2474 to 2774). Comparison of these sequences with those present in data banks permitted the identification of environmental isolates Lana A and Lana B as, respectively, a Sabin-like type 2 poliovirus and an intertypic recombinant poliovirus (Sabin-like type 2/wild type 1), both bearing a G instead of an A at nucleotide position 481. The two other environmental polioviruses were similar to the isolates from the paralytic cases. They were characterized by a peculiar 5'-UTR and by a VP1 region showing 98% homology with the Albanian epidemic type 1 isolates reported by other authors. This study confirms the environmental circulation in Albania of recombinant poliovirus strains, likely sustained by a massive vaccination effort and by the presence in the environment of a type 1 poliovirus, as isolated from the Lana River in Tirana about 2 months before the first case of symptomatic acute flaccid paralysis was reported in this town.

In order to implement a community-based rehabilitation programme in the rural district of Lezha (Albania), a systematic survey to assess disabilities and related care needs of people under 18 years of age was carried out. The aim of the survey was to evaluate the prevalence rates and severity of disabilities, detected by means of a questionnaire issued by the WHO Community-Based Rehabilitation Programme. The prevalence of disabled people under 18 years of age was 5.86 per 1000 (180 subjects out of the estimated population of 30,712). The most frequent diagnosis was sequelae of infantile cerebral palsy (1.8 per 1000), followed by mental retardation and deafness. The results of the survey stress that the severe non-self sufficiency of these subjects could be improved by means of an appropriate programme to increase their autonomy, including rehabilitation treatment and early school attendance.
